Re: Equipment designed and manufactured for use in-house
It is my understanding that the protection requirements apply, and it is also necessary for the technical documentation to be available, but that it is not necessary to actually put the logo on the product or prepare a D of C. I have a liaison committee minute from HSE which appears to state, in effect, that CE marking takes precedence over the Provision and Use of Work Equipment Regulations; in other words you can't claim exemption from CE marking on the basis of equipment falling under PUWER. However, it's not entirely clear from the document the extent to which one has to go. For reasons connected with another project I am involved in I have today officially asked the HSE for their position on this matter, and when I receive a reply I will post details to the list.

RE: Question on internal ESD testing
Jack, I also remember instances of a charge being developed internally from the movement of paper along the "paper-path" of the copier. At that time I utilized internal ESD discharges. Henry E.

A scenario where ESD can cause a genuine problem (in our business) is when someone walks across a room to add paper to a printer tray. In some machines, the unit will be in standby mode. In others, it may continue printing from a different tray or cabinet. In either case, a discharge to the internal metal parts of the paper tray could conceivably cause problems we would consider failures (and have).
